Introduction: The Importance of Aux Valve Controls in Skid Steer Loaders
In modern construction, landscaping, and agricultural projects, skid steer loaders are indispensable tools for a wide range of tasks. Among the most popular machines in this category is the Bobcat S205, known for its compact design, powerful performance, and ability to handle a variety of attachments. One of the critical systems in any skid steer loader is its auxiliary valve control system, which is used to operate hydraulic attachments such as augers, hydraulic breakers, and forks.
The auxiliary valve control system is vital for allowing the loader to interact with hydraulic tools and attachments, offering flexibility and versatility to operators. In this article, we will explore the auxiliary valve controls of the Bobcat S205, including their functionality, common issues, and how to ensure optimal operation.
What are Aux Valve Controls?
Understanding Hydraulic Systems
Before delving into aux valve controls, it's important to understand the hydraulic system of skid steer loaders. Hydraulics use fluid pressure to power attachments and other moving parts of the machine. The system comprises a hydraulic pump, valves, hoses, cylinders, and the fluid itself.
Auxiliary hydraulic systems, or aux valve controls, are an integral part of the loader’s hydraulic system. They provide the operator with the ability to operate attachments that require additional hydraulic flow, beyond what the loader’s primary functions (such as lifting and tilting) require. The aux valve control regulates the flow of hydraulic fluid to these attachments.
The Role of Aux Valve Controls in Bobcat S205
The Bobcat S205 comes equipped with an auxiliary hydraulic system that enables the loader to use various attachments. This system is governed by auxiliary valve controls, which direct hydraulic flow to specific attachments as needed.
The functionality of the auxiliary valve control system in the Bobcat S205 is designed to be intuitive, allowing operators to easily control the hydraulic flow to various attachments.
1. Flow Direction Control
The auxiliary valve allows the operator to control which direction the hydraulic fluid flows to the attachment. For example, when using a grapple, the operator can direct fluid flow to open or close the grapple. Similarly, when using an auger, the fluid can be directed to rotate the auger bit.
2. Flow Rate Control
For certain attachments like hydraulic breakers or tilting buckets, the flow rate must be adjusted to suit the specific demands of the tool. The Bobcat S205 can be equipped with a high-flow auxiliary system, which provides a higher flow of hydraulic fluid, enabling it to power more demanding attachments.
3. Control Lever or Joystick Operation
Most Bobcat S205 loaders use joysticks or switches to control the auxiliary valve. By pushing or pulling the joystick, the operator can adjust the flow of hydraulic fluid to the attachment, thus controlling its operation. Some models may have a foot control option for finer adjustments.
4. Quick Attachments
The ability to quickly connect and disconnect hydraulic attachments is another key advantage of the Bobcat S205. With the auxiliary valve control, the operator can easily switch between different attachments, such as a bucket, snow blade, or concrete breaker, ensuring efficient workflow and reducing downtime.
Common Issues with Aux Valve Controls and Solutions

2. Increased Productivity
With the ability to quickly switch between hydraulic attachments, operators can maximize productivity and reduce downtime. The aux valve control system ensures that all attachments operate efficiently and effectively.
3. Precision and Control
The auxiliary valve control system provides precise control over hydraulic attachments, enabling operators to perform tasks with greater accuracy and efficiency. Whether digging, lifting, or breaking concrete, the system ensures smooth operation and reduced risk of operator fatigue.
Conclusion: Mastering the Bobcat S205’s Auxiliary Valve Controls
The Bobcat S205’s auxiliary valve controls offer tremendous flexibility and power, enabling the skid steer loader to perform a wide range of tasks efficiently. By understanding how the system works and performing regular maintenance, operators can ensure that the machine remains in optimal condition, boosting productivity and minimizing downtime. Proper training and the use of compatible attachments will allow operators to get the most out of their Bobcat S205, making it an invaluable tool for a variety of industries, from construction to landscaping.

The Role of Aux Valve Controls in Bobcat S205
The Bobcat S205 comes equipped with an auxiliary hydraulic system that enables the loader to use various attachments. This system is governed by auxiliary valve controls, which direct hydraulic flow to specific attachments as needed.
- Single-Function Aux Controls: These controls allow for the operation of basic attachments such as grapples, brooms, and brush cutters, where only one hydraulic function (such as opening and closing) is required.
- Multi-Function Aux Controls: For more advanced attachments like hydraulic augers or power tilt buckets, which require multiple hydraulic functions simultaneously (e.g., tilting and rotating), the multi-function auxiliary controls enable smooth and precise operation by managing multiple flow paths.
- Auxiliary Hydraulic Control Valve: This is the heart of the system. It directs hydraulic fluid from the pump to the desired attachment. The valve is typically controlled by the operator using joystick or toggle switches.
- Auxiliary Ports: These are the hydraulic outlets located at the front of the loader where attachments are connected. Depending on the configuration, the Bobcat S205 can have a standard flow or high-flow auxiliary circuit.
- Flow Control: This component regulates the speed and pressure of hydraulic fluid sent to the attachment. Proper flow control ensures that the attachment operates at optimal performance without overloading the hydraulic system.
- Hydraulic Lines and Connectors: The hydraulic hoses that connect the auxiliary valve to the attachments must be durable and able to withstand high pressures. Quick-connect couplers are commonly used for easy attachment changes.

Common Issues with Aux Valve Controls and Solutions
1. Low Hydraulic Pressure or Flow
If the hydraulic system is not providing sufficient pressure or flow to the attachment, the problem could be with the auxiliary valve or the hydraulic pump. Common reasons include:
- Clogged Hydraulic Filters: Hydraulic filters can become clogged over time, restricting the flow of fluid. Regularly changing the filters will help maintain proper pressure.
- Worn-out Valves: If the auxiliary valve is not functioning properly, it can result in inconsistent fluid flow. Replacing or repairing the valve can restore normal operation.
- Hydraulic Leaks: Leaking hydraulic hoses or connections can cause a drop in fluid pressure. Inspecting the system for leaks and replacing damaged hoses is crucial.
Sometimes, the attachment may not respond properly to the aux valve controls, which can be caused by:
- Improper Flow Settings: If the flow rate is set too low for the attachment, it will not operate as intended. Adjusting the flow settings can improve attachment response.
- Faulty Couplers: If the hydraulic quick-connect couplers are dirty or damaged, they may not allow proper fluid flow. Cleaning or replacing the couplers can resolve this issue.
If there is no hydraulic power to the attachment, the cause might be:
- Disconnected Hydraulic Hoses: Ensure that the hydraulic hoses are properly connected to the attachment and the machine.
- Faulty Control Switches: If the control switches or joysticks are malfunctioning, the hydraulic system may not engage. Inspecting and replacing faulty switches can fix this issue.
1. Regular Maintenance
Regular maintenance is essential for the longevity of the Bobcat S205 and its auxiliary valve system. Some tips for maintaining the system include:
- Lubricate the Hydraulic Hoses: Regularly lubricating the hydraulic hoses and fittings prevents wear and tear, ensuring smooth operation.
- Inspect Hydraulic Filters: Replace hydraulic filters according to the manufacturer’s recommended schedule to prevent clogging and ensure maximum fluid flow.
When using hydraulic attachments, always ensure they are compatible with the flow rate and pressure settings of the Bobcat S205. Using an attachment designed for a high-flow system on a standard-flow machine can result in poor performance and potential damage to the hydraulic components.
